Shopping app lets you beam payments to old-fashioned cash registers

Groqit barcode scanner has your hippocampus' back

C'mon, we've all done it. Standing vigilantly in front of the DVD section, our mind races to remember whether or not we already own Land Before Time 11: Invasion of the Tinysauruses, and in a fit of frustration, we make the purchase anyway only to come home and find it sitting peacefully in one of the thirteen movie racks. If that hits home, you should definitely take a peek at Groqit -- a handheld barcode scanner that prefers to be called a "personal inventory management system." Owners simply scan in every book, CD and DVD they own, take it along for any future shopping sprees and use it to tell whether or not they've already purchased a given title. It should be noted, however, that it doesn't play nice with jewel cases, but apparently, the manufacturer thinks the $95 price tag more than compensates. Honestly, is the return process that much of a hassle?
